ANDREW STARK, OF CHICAGO, ILLINOIS.

GRAlN-HARVESTER.

SPECIFICATION forming part of Letters Patent No. 357,640, dated February 15, 1887.

' Application filed November 3, 1884. Serial No. 147,143. (No model.)

To all whom it may concern.-

Be it known that I, ANDREW STARK, a citizen of the United States, residing at Chicago, in the county of Cook and State'of Illinois, have invented certain new and useful Improvementsin Grain-Harvesters, which are fully set forth in the annexed specification.

This invention relates to certain novel fea tures and details of construction of the driving mechanism of h arvesting-machines, all of which are fully described, and set-forthin the claims.

Figure 1 is a plan of the drive-wheel, main frame, and gearing. Fig. 2 is a frontelevation of the same. Fig. 3 is a plan, Fig. 4 is an inside elevation, and Fig. 5 is a vertical section, of the main driving-pinion frame and the gearing bearing thereon. Fig. 6is an outside elevation of the outside divider, grain-wheel, and bearings. Fig. 7 isa plan, and Fig. 8 is an outside elevation, of the casting which secures the outside divider to the fingerbar.

Fig. 9 is an outer elevation, and Fig. 10 is a plan, of the grain-wheel bearing-piece.

A is the driving-whecl. A is the drivinggear thereon.

B is the main frame.

O is the main driving pinion frame or bracket.

0 is the main driving-pinion.

D is the inner segment, which is secured to the cross-bar B of the main frame. To the same inner segment, D, is secured the main driving-pinion frame or bracket 0, which is also further secured at c to the cross-bar B of the main frame. The main driving-pinion O, which meshes with and is driven by the main driving-gear A, is fast on its own shaft 0", which has its bearings in the main drivingpinion frame or bracket 0. Said shaft is clutched to the bevel gear-wheel G, which meshes with the bevel-pinion G, the shaft of which is journaled in the main driving-pinion frame 0 at right angles with the shaft 0, and has at its rear end a crank, G which drives the sickle, and carries also, between the pinion G and the crank G, the sprocket-wheel G from which power may be communicated to the conveying and binding mechanism. (Not illustrated.)

It will be noticed that the main frame B is made of a continuous iron, B B B, extending from the finger-bar B to which it is attached at the point 1), around the wheel to the rear sill, B, to which it isjoined at the rear outside cornenb". I have so shaped this iron frame that the part B, from the finger-bar to the angle 1), is in proper 'position and at a suitable angle to serve as the inside divider, thereby obviating the necessity for any additional device for that purpose.

M is the outside divider, its rear portion, M, being the end-board of the platform.

N is the grain-wheel bearing and guiding lever, and N the grain-wheel.

P is a bracket, which serves the triple purpose of securing the outside divider to the finger-bar, affording secure attachment for the grainwheel bearing and guiding lever, and

being or having rigid with it the grain-wheel guide. This bracket P has the stubblew'ard projection or lug p, to which the finger-bar is bolted. Integral with this lug is the last sickleguard, 16. The bracket 1? has also the projection or boss 1) in line with the finger-bar, and bearing the pivot of the grain-wheel guidinglever N. It has also the forward projection, 1), and the rearward projection, p, to both of which the outside divider and endboard, M M, is secured. It hasalso extended rearward the segmental guide 10 for the grainwheel, the additional guide-pulley or guidestnd 19 for the said platform supporting and adjusting cable W, the guide f being at the end of the finger-bar and in line therewith. so that it receives the cable W, which lies under the finger-bar, and is guided to and retained in that position by the guide-pulley (l on the lower end of the inner segment at the other end of the finger-bar. This arrangement of the finger-bar with relation to the segment and the bracket P, with the guides placed as stated, causes all the strain upon said cable in sustaining the platform to be exerted upon the rigid finger-bar in the direct-ion of its length, whereby is prevented any straining or wrenching of the platform or any connected parts of the machine, since both guides-that on the segment and that on the bracket-are fixed on iron, which is bolted directly to the iron finger-bar which connects them, and in the direction of Whose length the strain is applied.

The means foradj usting the frame and platform herein illustrated and partly described are not designed to be claimed herein, but are made the subj eet ofmy application No. 102,762, filed August 4, 1883.

In order to render the segment on the inside of the wheel, to which all the driving-gearing is connected, the gear-frame being affixed directly to the segment, as above described, as rigid as possible, in addition to having it sceured directly to the finger-bar B, which is itself secured at two poi nts to the main fram eviz., at b and b I extend from the upper end of the segment, grainward and downward to the inner side of the main frame, the upper frame-bar, B, of three-eighth-inch iron, rigidly boltedboth to the segment and to the main frame. This frame-bar serves as a support for any gearing which it may be necessary to mount upon the upper part of the machine to drive either a hinder or in some cases the reel.

The finger-bar, axle-guide, and main frame, each rigidly and directly secured to both the others, the general construction of the main frame comprising the iron frame-bar passing around the front, outer side, and rear of the drive-wheel, and having the cross-bar inside the latter,and the inner segment secured to the crossbar, and the finger-bar secured to both the segment and the main frame, I do not claim herein, because I have claimed such construction in my application No. 174,698, filed August 18, 1885, which was a division of my said former application No. 102,762, filed August 4, 1883.

I claim- 1. In aharvesting-machine, in combination with the platform and the finger bar, the bracket P, adapted to be seen red rigidly at the end of the finger-bar, and having integrally therewith the front and rear attachments for the outside divider, the pivot for the grainwheel guide-lever, and the segmental grainwheel guide, substantially as set forth.

2. In a harvesting-machine, in combination with the main frame, the crossbar rigid therewith and extending from front to rear inside the drive-wheel, the inner segment rigidly secured to the cross-bar, the finger-bar rigidly secured to both the main frame and the lower end of the inner segment, and the upper framebar secured rigidly to the upper end of theinner segment and to the inner side of the main frame, and thereby bracing the segment, substantially as set forth.

3. In a harvesting-machine, in combination with the iron main frame secured rigidly to the finger-bar, and extending thence forward around the front, outside, and rear of the driving-wheel, and the cross-bar inside the driving-wheel rigidly secured front and rear to the main frame, and the inner segment secured to the cross-bar and to the finger-bar, the upper frame-bar secured rigidly to the upper end of the inner segment and to the inner side of the main frame.

4. In a harvesting-machine, in combination, substantially as hereinbefore set forth, the inner segment, the finger-bar, and the grainwheel guide, the segment and the grain-wheel guide being both rigidly and directly secured to the finger-bar.

5. Ina harvesting-machine, in combination, the inside segment, the grain-wheel guide, and the finger-bar, the segment and grain-wheel guide being both secured directly and rigidly to the finger-bar, and having, respectively, the inside and outside guides for the platformsupporting cable.

6. Inaharvesting-machine, in combination, as set forth, the iron main frame secured to the finger-bar, and extending thence forward around the front, outside, and rear of the driving-wheel, a cross-bar rigidly secured to the front and real-sides of the main frame inside the wheel, the inside segmental axle-guide rigidly secured to the finger-bar and to the cross-bar, and the main driving-pinion frame rigidly secured to the segmental axle'guide and to the cross-bar.

7. In a grain-harvester, in combination with the fingerbar and the outside divider, the bracket rigidly and directly secured to both and forming the connection between them, and having both the bearing and the guide for the grain-wheel guidinglever, substantially as set forth.

8. In agrain-harvester, in combination with the finger-bar, the bracket P, havingintegrally therewith the supports for the outside divider, and the outside finger or sickle guard, substantially as set forth.

In testimony whereof Ihave hereunto set my hand, in the presence of two witnesses, at Ghicago, Illinois, this 2d day of July, A. D. 1884:.

ANDREWV STARK.
